Handmade shaker stickers. They are approximately 2.5cm in size, and come in a set of 8. These are not commercially available, so they are unique and very popular for children's sticker swaps! They are hard case-like stickers that don't dent when pressed. The capsules are glued shut and will not open. The backs are stickers with adhesive. Please understand that these are handmade items before purchasing.
